om BURNER.

application filed April 20, 1926. Serial No. 103,306,

The present invention relates to oil lourners, and Vmore particularly to a burner of the openfretort type utilizing a naturaldraft. An object of the present invention is to provide anoil burner capable of producing a blue flame when used on a high and on a low "lire and which `is of the open vretort type utilizing natural draft" andi" gravity feed, and a burner which produces practically no smoke or carbon, and one which requires no cleaning or `other attention duringY its long 1continued use.

`Another object of the invention is to pro vide a burner with means for so distributing a natural draft that butasmall draft isr"equire`d, and which consumes completely `and thoroughly a relatively small amount of oil but which `at the same time produces a relatively yhet flame.

` A further object .of the invention is to provide a burner with an improved wiclr fand spreader, theisarne `comprising a wire encasedgin asbestos and supporting a layer of wood ashes, utilizing theprinciple of the oil adhereing to and following metal vmore readilythan ashes so to first spread the oil. vand subsequently effect the absorp- `ti'onof the oilfby the lashes to vaporize the ashes, particularly under the influence of heatfor distribution tothe draft of air directed over the upper surface level of the ashes.

A further feature of this invention is to provide means of draft for enveloping the inner and outer sides of the burner, particu larly when ythe draft is high or at `full force, to eliminate vibrationland back pressure `in theburner and automatically takes care of Athe n draft under all weather conditions in VSupplying the proper amount of oxygengto produce the blue llame and a quiet llame which will not dicker.

The invention also aims to provide means drain olf excess quantities of oilv to` prevent oil from overflowing the burner.V y

The invention also provides an improved draft ring to insure the proper admission of air to the burner even when the saine is packed, `particularly when Athe burneris iin- "stalled in furnaces and the like.

` The above and various other vobjects and advantages of this invention will inpart be described in, and in part be understood from the following detailed description of the through an oil burner yto the present invention, and

rbase plate of `hase ring` 10 is portion upon` the upper edge of a pan `the-hase ring 10.

Referring to the drawing, 10 designates 'a ring form having a central air opening' 11 and which at its upper 'side is dished out to provide a gene-rating cup 12 extending `annular-ly in tliebase ring. The supported at `its outer edge which is provided with an outstanding flange about its upperedge extending beyond The pan 13 is thus relatively large and isadaptedto catch the overflow from the burner, the inner marginal lflange 15 of the base ring 10 being lof less flange or wall to permit of the overflow ofthe oil into the over- Arranged about the overflow pan 13 `is a downwardly curved draft ring its upper edge to the flangelll the like.' This draft ring 16 at `its lower edge stands outwardly aboutthe pan 13and provides a free air passageabout the pan, the air entering the pan through relatively large draft openings 18 formed thepan. Surniounting the base ring 1() and supporte'dthereby'is an oil ring .19 of ring form providing through the center thereof.

a draft passage `20 upwardly The draft passage 2O is of smaller diameter than/the draft passage 11 in the base ringand the oil ring 19 slightly overlaps the inner edge portion of the base ring `10.` The draft ring 19 isV provided with a depending outwardly curved supporting .flange 21 which seats in the generating cup 12 of the base ring 10 and spaced openings 22 in its lower edge to establish communication in the generating cup between the opposite sides of the supporting flange 21'. `This admits free passage of air and oil beneath the oil ring and over the inner edge of the base ring `The oil ring 19 is zUsshaped in cross section to provide `a relatively deep annular trough, and fitting' in this trough is au inner lining' 23 of similar shape .but `havingl outturned flanges 24 at its upper inner and outer lli) marginal edges to seat upon the upper neath the disk 31 I a spreader Capor disk edges of the draftring 19. in the bottom of this draft ring 19, so formed. is placed a ririg of asbestos 25 wrapped about a core of wire 25, and fitting in the draft ring above the asbestos 25 is a body of wood ashes 27 or Ihe like which is levelled with theupper edge of the draft ring.

An oil feeding pipe 28 is carried upwardly int-o the draft ring 16 and through one side ofthe overflow pan 18, the pipe 28 being thence carried upwardly through the draft opening 11 at one side thereof and opens vinto the bottom of the oil ring 19. The oil ring 19 is provided in its draft opening 2O with a cross bar 29 extending across the lower edgefof the draft rijngqand whichsupports a threaded stem 30 which extends upwardly throughv the draft opening 2O and supports 31. The disk 31 extends in overlapping relation at its outel edge with respect to the oil ring 19 and terminates inwardly of the outer edge thereof, and completely covers the upper end of the draft opening 2O so as to spread and direct the upwardly flowing air outwardly over the upper surface of the body of wood ashes 27.

ln the operation of the-burner, oil enters through pipe '28 into the bottomV of the oil ring 19 and is absorbed by the vasbestos 25 and is broken up by contact with the wire core 26. The oil follows the wire core 26 and is evenly distributed about therbottom of the annular oil ring 19 ast-he oil will follow the metal more readily than the ashes. The oil, being broken up7 enters the body of wood ashes 27,.and when the same are heated7 the oil is vapor-ized and such vapor is permitted to escapeat the upper surface of the body of ashes 27 and is brought into con tact with the air which is passing` from beand over the oil ring 19.

. The openings 22 in the base 21 of the oil ring 19 admit free air to pass around burner when the draft is high and thus checks vibration or back pressure in the burner7 this being an important feature of the present burner and effecting the automatic regulation of the draft under all kinds of weather conditions and admitting the proper amount of oxygen at alln times to produce the steady blue flame.

It will be noted that the overflow pan is below the air inlet and is tireproof and is relatively largefas it extends to the outer edge of the base ring 10 so as to catch all overflowing Voil and prevent the oil from dripping outwardly `frown the burner. The overflow pan 18 is provided with a drain pipe 32 suitably located to carry off any excess oil which may accumulate in the bottom of the pan.

The provision of the draft ring 16 insures a complete draft through the burner at all times and prevents the draft being shut off particularly when packing or the like is used about the burner in certain installations, such as in furnaces and the like as the draft ring 16 protects the draft openings 18 in the outer wall of the overflow pan 13.

The'above described burner is adapted for Vinstallation and use in b1 coders, heaters, furnaces, boilers and wherever heat is required and a lsmall amount of draft is available.

It is of course understoodthat various changes and modications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
